URlNAL-BASIN WASTE-PIPE.

Specification of Letters Patent.

Patented Oct. 9, 1906.

Application filed August 18, 1905. Serial No. 274,720.

' simple basin in which the discharge-pipe and vent-pipe are in avertical line with each other inside the basin, and the former may beeasily lifted to allow sediment to flow out.

With this object in view my invention con sists in the construction andcombination of parts, as hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a vertical cross-section of myimproved device, and Fig. 2 is a cross-section of a part thereof.

a represents the basin or bowl, and b the waste-pipe. The bowl is cutaway for the reception of the tubular holding-piece having the topflange c, which holding-piece is screwthreaded at its lower end, a nut dengaging said holding-piece and said waste-pipe, thus securing thelatter in place. 6 is a packing between said nut and the bowl.

f is the discharge-pipe, beveled at g, to fit within acorrespondingly-shaped recess in the holding-piece. Its lower edge isscalloped, as shown at h, to provide'passages for the escape of sedimentand liquid when the tube is raised. The upper part of the tube f isbored out, as shown at i, so that it will slide on the tube m, whichserves as a vent for the gases. is a hood or bell secured to the tube fin any desired manner, as by screw-threads and the lock-nut is,extending down into the bowl a and provided with guiding and strainmgarms L.

"m is the vent-tube, removedly secured to the tube f by a union-joint n.The tube f is provided with a number of drainage-perforations p, locatedwithin the bell when the latter is in position.

The ordinary operation will be evident from the description; but when itis desired to remove sediment the unionjoint n is loosened and the tubef, carrying the bell j, is slid upwardly upon the stationary tube m,which closes the perforations p, thus preserving the gas-seal.

The advantages of the construction shown are that the waste-pipe andvent-pipe are located in a straight line in a vertical plane, so thatgases can readily escape and the wastewater flows evenly on all sides ofthe tube. The trap can be cleaned better and more easily. All foreignmatter as matches, for eXampleis prevented from flowing down thewaste-pipe. The strainer and overflow devices are all combined in onestructure. The whole device can be easily lifted to allow sediment toflow out and at the same time a tight gas-seal is provided.

Having thus described my invention, I claim 7 1. In a urinal-basin, thecombination of a bowl provided with a waste-pipe, a vent-tube supportedin line with said waste-pipe and a perforated tube slidably mounted onsaid vent-tube, said perforated tube having a depending bell attachedthereto, substantially as described.

2. In a urinal-basin, the combination of a bowl provided with a verticalwaste-pipe, a vertical vent-tube located above and in line with saidwaste-pipe, and a strainer device provided with perforations locatedjust below said vent-pipe, said strainer device being slidably mountedon said waste-pipe, whereby the upward movement of the strainer devicewill cause the perforations therein to be closed by the vent-tube, thuspreserving the gas'-seal, substantially as described.

3. In a urinal-basin, the combination of a bowl provided with awaste-pipe, a vent-tube in line with said pipe, and a tube provided withperforations, with a scalloped lower end, and with a strainer device,slidably mounted on said vent-tube, substantially as described.

4. In a urinal-basin, a strainer device, in cluding a tube open at bothends and having its upper part bored out and provided with perforationsnear its upper end and with scallops at its lower end, a depending bell,provided with arms near its lower edge, and

means for securing said bell to said tube, and ascalloped end and abell,substantially substantially as described. as described. 10

5. In a urinal-basin the combination of a In testimony whereof I aflixmy signature bowl provided with a Vertically-arranged in presence of twowitnesses.
